Telophase I is the final stage of the first division of meiosis, a process that reduces the chromosome number in reproductive cells. During this phase, the separated homologous chromosomes reach opposite poles of the cell. The nuclear envelope begins to reform around each set of chromosomes, which may also start to decondense. Following telophase I, the cell undergoes cytokinesis, resulting in two daughter cells, each with half the original chromosome number. These cells are now haploid, containing one set of chromosomes, and will proceed to meiosis II for further division.
